ABSTRACT:
The present invention relates to a folder or hinge type portable terminal having a grounding unit. A main body has a main board. A folder opens and closes at an angle from the main body. At least one component of a hinge module is formed of a metallic material, and opens and closes the folder at an angle from the main body. A connecting means selectively contacts a grounding portion of the main board to the material components of the hinge module in response to the opening and closing operation of the folder, to provide optimal antenna radiation characteristic irrespective of the opening and closing operation of the folder.
